A valve adaptor for a sealing/pump-up device, capable of releasing air in a tire without releasing a sealing agent remaining in the device. As shown in Fig. 1 (A) , when the valve adaptor (76) is set to a second state, a pressing member (84) pressed by a coil spring (84) opens an on/off valve (28) of a tire valve (16). When the on/off valve (28) is opened, air released from the inside of the tire flows between an opening edge (24) of the tire valve (16) and a packing member (80) and is released to the outside after flowing in a through groove section formed in a screw thread section (78A). Pressing force of the coil spring (84) causes the packing member (80) and an intimate contact section (88) to be in intimate contact with each other, and this prevents the sealing agent and air from being released from a fluid supply hose to the outside. Thus, setting the valve adaptor (76) to the second state allows the air in the tire to be released without releasing the sealing agent remaining in the device. |
